Key Features
- 10 ohm impedance at 100 MHz with 1000 mA rated current enables effective EMI filtering on high-current power rails in 0402 package
- 25% impedance tolerance in miniature 0402 chip ferrite bead format ideal for space-constrained mobile and wearable PCB layouts
- SMT (surface-mount) construction compatible with standard reflow soldering for seamless integration into automated PCB assembly
Applications
The Z0402C100ASMST is used in power management circuits, DC-DC converter output filters, and high-frequency RF front-end designs where broadband EMI suppression is needed at up to 1000 mA current. Its 10 ohm impedance at 100 MHz efficiently attenuates switching noise and RF interference without significant DC voltage drop. The compact 0402 footprint makes it a preferred choice for consumer electronics, IoT modules, and portable device power rails.

Frequently Asked Questions
What impedance does the Z0402C100ASMST provide at 100 MHz, and what current rating does it support?
The Z0402C100ASMST provides 10 ohms of impedance at 100 MHz with a 25% tolerance, and is rated for up to 1000 mA of continuous DC current. This combination allows effective high-frequency noise suppression on power rails without causing significant resistive losses at rated load.
For which PCB form factors is the Z0402C100ASMST most appropriate given its 0402 package size?
The 0402 chip package measures approximately 1.0 mm x 0.5 mm, making the Z0402C100ASMST an optimal choice for compact designs such as smartphones, wearables, IoT sensors, and Bluetooth modules where board area is limited. The SMT footprint allows placement alongside 0402 capacitors and resistors in standard high-density layouts.
How does the Z0402C100ASMST compare to a 0603 ferrite bead of similar impedance for DC-DC converter output filtering?
Both the 0402 Z0402C100ASMST and equivalent 0603 ferrite beads offer 10 ohm impedance at 100 MHz, but the Z0402C100ASMST occupies 40% less board area, which is critical in miniaturized designs. However, if the application requires more than 1000 mA or the PCB requires improved handling during assembly, a 0603 or larger package may be preferred for its mechanical robustness.
