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

What are the key design constraints when integrating the 1210J6306P80CCR Knowles Syfer capacitor into high-voltage RF matching networks or precision oscillators?
The 1210J6306P80CCR from Knowles Syfer offers 6.8 pF ±0.25 pF in a 1210 package with C0G/NP0 dielectric, providing stable capacitance across temperature and voltage. Engineers should evaluate the self-resonant frequency determined by the low parasitic inductance of the 3.20 mm x 2.50 mm x 2.00 mm max dimensions, ensure PCB pad layout minimizes additional inductance, and confirm that peak voltages remain within the 630 V rating under RF swing to maintain linearity and avoid dielectric stress.
How does the 1210J6306P80CCR perform in terms of power handling and ESR when used in resonant tank circuits for DC-DC converters?
In resonant applications, the 1210J6306P80CCR leverages the inherently low dissipation factor of C0G/NP0 dielectric, resulting in low equivalent series resistance that supports efficient energy transfer with minimal self-heating. Designers need to calculate RMS current based on the circuit's operating frequency and ensure thermal dissipation through the large 1210 footprint keeps the component within the -55°C to 125°C operating range during continuous operation.
Can the Knowles Syfer 1210J6306P80CCR be used in applications exceeding 125°C ambient temperature, and what factors influence suitability?
The 1210J6306P80CCR is specified for operation from -55°C to 125°C. Beyond this range, capacitance stability may deviate from the tight C0G/NP0 limits, and long-term insulation resistance can degrade depending on the thermal profile and applied voltage derating. For boundary conditions near 125°C, engineers typically apply voltage derating and verify performance through extended temperature cycling specific to the end-use environment.
What considerations apply when evaluating the 1210J6306P80CCR as a replacement for older 1206 or 1210 C0G capacitors from other manufacturers in legacy designs?
When migrating to the 1210J6306P80CCR, compare the exact tolerance of ±0.25 pF, 630 V rating, and physical dimensions (3.20 x 2.50 x 2.00 mm max) against the existing part. The larger 1210 case may require footprint verification, while the C0G dielectric behavior remains consistent; however, differences in electrode configuration or termination materials can affect high-frequency parasitic elements and solder joint reliability in vibration-prone assemblies.
In high-reliability industrial systems requiring long-term stability, what operating condition factors should be reviewed for the 1210J6306P80CCR?
For extended service life, the 1210J6306P80CCR benefits from the negligible aging characteristic of C0G/NP0 dielectric. Engineers assess applied DC or AC voltage relative to the 630 V rating, humidity exposure given the MSL 1 classification, and mechanical board flexure during thermal excursions, as these influence insulation resistance and potential microcrack formation over time in continuous industrial operation.
What I/O voltage and configuration aspects need attention when using the 1210J6306P80CCR in mixed-signal or high-impedance analog circuits?
Due to its tight ±0.25 pF tolerance and stable C0G/NP0 (1B) coefficient, the 1210J6306P80CCR suits high-impedance nodes where capacitance variation directly impacts signal integrity or filter response. Designers verify that the surface-mount 1210 package termination supports the assembly process without introducing contamination that could affect leakage in sensitive analog paths, and confirm voltage stress stays well below 630 V for linear operation.
Are there specific application boundaries where the 1210J6306P80CCR from Knowles Syfer would require additional derating or alternative selection compared to higher-voltage parts?
In circuits with sustained peak voltages approaching or combining DC bias with AC ripple near 630 V, the 1210J6306P80CCR operates closer to its design limit, potentially necessitating derating or series/parallel combinations to distribute stress. Its general-purpose C0G rating in the 1210 size fits precision filtering or coupling but may prompt review of parts with thicker dielectrics or larger cases when extreme overvoltage transients are anticipated.
When migrating from film or porcelain capacitors to the 1210J6306P80CCR in space-constrained designs, what trade-offs arise?
The 1210J6306P80CCR provides a compact surface-mount alternative with stable 6.8 pF ±0.25 pF and 630 V capability, reducing board area compared to many leaded film types. Trade-offs include evaluating differences in self-inductance, thermal mass, and mechanical robustness; the MLCC construction offers lower ESR at high frequencies but requires attention to solder reflow profiles and board-level strain to achieve comparable long-term reliability in the target environment.
