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

Can CRCW080521K5FKTC be used as a pull-up or pull-down resistor in automotive control circuits?
CRCW080521K5FKTC is a 21.5 kOhm, 1% 0805 thick-film resistor with AEC-Q200: qualification, so it is commonly used for input biasing, default states, and divider legs in automotive electronics. Check the target pin leakage current, noise margin, and wake/sleep current budget, because 21.5 kOhm may be too weak for noisy inputs or too strong for ultra-low-power nodes.
How much power margin should I leave when using CRCW080521K5FKTC in a high-temperature enclosure?
CRCW080521K5FKTC is rated at 0.125 W under standard conditions, but the usable dissipation drops as ambient temperature rises and depends on PCB heat spreading. For continuous operation, calculate dissipation from V^2/R or I^2R and keep CRCW080521K5FKTC well below the nominal rating, especially in sealed or under-hood assemblies.
Is CRCW080521K5FKTC suitable for precision divider or feedback networks?
CRCW080521K5FKTC has 1% tolerance and a ±100 ppm/°C tempco, which works for many control and sensing circuits, but it is not a tight-accuracy part by itself. If divider ratio drift affects ADC accuracy, regulator setpoint, or calibration spread, evaluate the full network error across temperature before selecting CRCW080521K5FKTC.
What should I verify before replacing CRCW080521K5FKTC with RMCF0805FT21K5, ERJ-6ENF2152V, CRCW080521K5FKEA, or 9C08052A2152FKHFT?
For a practical replacement of CRCW080521K5FKTC, confirm the same 0805 footprint, 21.5 kOhm value, 1% tolerance, compatible power rating, and similar temperature range. Also check whether the substitute matches the AEC-Q200: requirement, termination finish, and package height, since those details affect automotive qualification and assembly fit.
Can CRCW080521K5FKTC handle surge or pulse loading in automotive or industrial circuits?
CRCW080521K5FKTC is a thick-film chip resistor, so it is well suited to steady-state biasing, but pulse energy still needs to be checked against the actual waveform. If the node can see ESD clamp events, inrush-limited paths, or load-dump-related stress, verify peak voltage, pulse width, and duty cycle rather than relying only on the 0.125 W rating.
Is CRCW080521K5FKTC a good choice for under-hood or long-life industrial use?
CRCW080521K5FKTC is specified from -55°C to 155°C and carries AEC-Q200, which makes it a reasonable fit for harsh-environment boards when the circuit stays within its electrical limits. For long service life, also review PCB contamination, humidity exposure, solder joint design, and nearby heat sources, since those factors affect the finished assembly more than the resistor body alone.
What PCB layout and assembly choices help keep CRCW080521K5FKTC reliable?
CRCW080521K5FKTC in 0805 format is normally straightforward to assemble, but reliability improves when the pads are symmetric, solder fillets are balanced, and the part is kept away from board edges, connectors, and flex points. If the board will see vibration or thermal cycling, avoid placing CRCW080521K5FKTC where mechanical strain concentrates.
Does CRCW080521K5FKTC fit designs that need RoHS-compliant sourcing?
CRCW080521K5FKTC is listed as RoHS non-compliant and REACH affected in the provided data, so compliance should be checked against the end product’s target market and documentation set. If the program requires a RoHS-compliant resistor, select a functionally similar alternative and verify its declaration before release.
