W2H11A2208AT1A

Overview

The W2H11A2208AT1A is a surface-mount feedthrough capacitor from the KYOCERA AVX W2H series. It features a capacitance of 22 pF with a tolerance of -20% to +50%. The device has a DC voltage rating of 100 V and a high current rating of 500 mA. Its maximum DC resistance is 150 mOhms, and it utilizes C0G (NP0) dielectric characteristics. The component is housed in an 0805 (2012 metric) package with four terminals, measuring 2.01 mm in length, 1.25 mm in width, and 1.14 mm in height. It operates within a temperature range of -55°C to +125°C.

Feature Summary

• High current handling capability up to 500 mA for robust power line filtering
• Broad frequency response providing high attenuation across RF spectrum
• Compact 0805 surface mount footprint for space-constrained designs
• C0G/NP0 dielectric ensures stable capacitance over temperature variations

Applications

• RF signal path filtering in communication equipment
• Power supply decoupling in high-frequency circuits
• EMI suppression in automotive electronic control units
• Noise reduction in industrial automation systems

Procurement Notes

Verify the specific suffix 'T1A' against the manufacturer datasheet to confirm packaging type and terminal finish specifications. Ensure the selected variant matches the required 500 mA current rating and 150 mOhm DCR limits for your circuit design. Confirm RoHS compliance status if restricted substances are a constraint. Cross-reference the 0805 package dimensions with your PCB footprint library to ensure mechanical compatibility during assembly.

Selection Notes

Select this component when high current capacity is required alongside precise RF filtering. The 500 mA rating distinguishes it from lower-current alternatives in the same family. The C0G dielectric is essential for applications requiring minimal capacitance drift. Consider the 0805 size relative to available board space. Verify that the 100 V DC rating exceeds the maximum operating voltage of the target circuit to ensure long-term reliability under stress conditions.

Part Context

This part belongs to the W2H series of high-current feedthrough capacitors. These components integrate capacitor and inductor functions into a single surface-mount device. They are designed to replace traditional discrete LC filters. The series offers improved performance in high-frequency noise suppression. KYOCERA AVX manufactures these components using multilayer ceramic technology.

Replacement Considerations

W2F11A2208AT1A is a parameter-equivalent alternative but has a lower current rating of 300 mA and higher DCR of 600 mOhms. Verify if the reduced current handling meets the application requirements before substitution.
