Packaging & ESD

Industry-standard static shielding packaging is used for electronic components.Anti-static, light-transparent materials allow easy identification of ICs and PCB assemblies.
The packaging structure provides electrostatic protection based on Faraday cage principles.This helps protect sensitive components from static discharge during handling and transportation.


All products are packed in ESD-safe anti-static packaging. Outer packaging labels include part number, brand, and quantity for clear identification. Goods are inspected prior to shipment to ensure proper condition and authenticity.

ESD protection is maintained throughout packing, handling, and global transportation. Secure packaging provides reliable sealing and resistance during transit. Additional cushioning materials are applied when required to protect sensitive components.

Frequently Asked Questions

In a high-voltage divider using HHV-25JB-52-7M5, how can I estimate the voltage rating given only the 0.25W power rating and 7.5 MΩ resistance?
For HHV-25JB-52-7M5, the theoretical maximum continuous voltage based on P = V^2/R is V ≈ sqrt(0.25 W × 7.5 MΩ) ≈ 1.37 kV. The actual working voltage will depend on insulation, coating, and creepage/clearance on your PCB. If your design approaches or exceeds this range, consider splitting the voltage across multiple HHV-25JB-52-7M5 devices in series or selecting a resistor with a higher voltage rating from the supplier. Always confirm the maximum working voltage from YAGEO’s official data for HHV-25JB-52-7M5 and account for safety margins in your design.
For a temperature-critical analog front-end, does using HHV-25JB-52-7M5 introduce large drift or offset across -55°C to 155°C?
HHV-25JB-52-7M5 has a temperature coefficient of ±200 ppm/°C. Across a 210°C span, ΔR/R ≈ 0.0002 × 210 ≈ 0.042, or about 4.2% change in resistance. That can translate to several hundred kilo-ohms of shift on a 7.5 MΩ value and meaningfully affect precision if the resistor is part of a critical gain or offset path. If tight accuracy is required over temperature, consider resistors with a lower TC or use a compensation scheme in the design, noting that the ±5% tolerance at 25°C will interplay with the TC across temperature.
If HHV-25JB-52-7M5 is scarce, what practical checks should I perform when selecting a replacement axial resistor with similar value and power rating?
When sourcing a replacement for HHV-25JB-52-7M5, ensure the alternatives meet: 7.5 MΩ ±5%, 0.25W rating, axial through-hole package, flame-retardant coating, and a similar temperature coefficient. Verify the maximum working voltage, lead dimensions, solderability, RoHS3 compliance, and coating compatibility with your environment. Also confirm mechanical fit (body size about 2.4 mm diameter × 6.3 mm length) and availability in bulk packaging if that matters for your assembly process.
What PCB layout considerations should I apply when integrating HHV-25JB-52-7M5 to minimize leakage and ensure safety in moist environments?
Plan for explicit creepage and clearance around high-voltage paths when using HHV-25JB-52-7M5, and consider conformal coating or potting in humid environments. Keep high-voltage nets physically separated from low-voltage nets, minimize surface leakage paths, and provide clean, dry mounting surfaces. If the coating is flame-retardant, verify that the coating process does not adversely affect solder joints or mechanical reliability during assembly and service.
Is HHV-25JB-52-7M5 appropriate for automotive or other harsh industrial environments, given its temperature range and packaging?
HHV-25JB-52-7M5 supports -55°C to 155°C and is RoHS3 compliant, but there is no stated automotive-grade (AEC-Q) qualification. For automotive or mission-critical industrial use, verify with YAGEO whether this exact part meets any relevant environmental or reliability standards, or select an automotive-qualified alternative. Consider vibration, humidity, long-term drift, and potential differences in leakage paths in harsh environments.
Can I reflow-solder HHV-25JB-52-7M5, or is it strictly through-hole assembly?
HHV-25JB-52-7M5 is specified as a through-hole axial resistor. It is typically soldered by hand or with wave/reflow processes designed for through-hole parts. If reflow is used, ensure the soldering profile is compatible with the flame-retardant coating and the axial lead construction. If your process is strictly surface-m mount, you will need a different package that matches your board.
What impact does the axial lead package and associated parasitics of HHV-25JB-52-7M5 have on high-frequency circuits or precision RC timing networks?
Axial metal-film resistors contribute small parasitic capacitance (a few picofarads typical) and lead inductance observed in high-frequency cases. In precision RC timing networks or high-frequency paths, these parasitics can shift time constants or bandwidth, particularly when the resistor value is large (7.5 MΩ). If your application operates at tens of megahertz or higher, validate the device’s parasitics from the datasheet or consider a purpose-built high-frequency resistor with known characteristics.
How does the flame-retardant coating on HHV-25JB-52-7M5 affect solderability, cleaning, or recalibration in a precision system?
The flame-retardant coating can influence solder wetting near the body; use appropriate flux and controlled soldering temperatures to avoid coating damage. After soldering, verify cleanliness compatible with the coating, and re-calibrate if your design is sensitive to small shifts at the leads or body. When replacing or reworking, avoid excessive heat that could degrade the coating and local resistance, and re-check the circuit’s performance after assembly.
What procurement considerations apply for HHV-25JB-52-7M5 in terms of packaging, lead times, and handling for bulk orders?
HHV-25JB-52-7M5 is listed as Bulk packaging, which means there is no tape-and-reel for automated placement. Plan for manual assembly or arrange for alternative packaging if your supply chain relies on reels or trays. Confirm current stock, lead times, and whether the supplier can provide a version with the same electrical specs in a packaging suitable for your manufacturing flow, while maintaining RoHS3 compliance.
