DSS1NB32A103Q55B

Overview

The Murata DSS1NB32A103Q55B is a three-terminal feedthrough capacitor from the DSS1 series, designed for EMI/RFI suppression. It features a capacitance of 0.01 µF with a ±10% tolerance and a DC voltage rating of 100 V. The component supports a maximum current of 2 A and operates within a temperature range of -40°C to +85°C. It utilizes a radial leaded package with a 2.54 mm pitch, measuring 7.5 mm in height, 8.5 mm in length, and 3.5 mm in width.

Feature Summary

• Three-terminal feedthrough architecture providing low parasitic inductance for effective high-frequency noise attenuation
• Compact radial leaded form factor enabling direct mounting on standard 2.54 mm pitch PCBs
• Integrated bead construction combining filtering and isolation functions within a single small component

Applications

• Power supply input/output filtering in compact electronic devices
• EMI suppression for signal lines in automotive electronics
• Noise reduction in industrial control systems requiring robust thermal performance

Procurement Notes

Verify the specific suffix Q55B against official Murata documentation to confirm the exact packaging type and terminal configuration. Ensure the selected variant matches the required 2.54 mm pitch and 2 A current rating for your circuit design. Cross-reference the RoHS compliance status with the latest manufacturer datasheet before finalizing procurement specifications.

Selection Notes
