SIM82121Y5A032

Overview

The SIM82121Y5A032 is a ferrite bead manufactured by Meritek, designed for electromagnetic interference (EMI) suppression in electronic circuits. It features an 1812 surface-mount package and supports a single circuit configuration. The component exhibits an impedance of 120 ohms at a frequency of 100 MHz. It is RoHS compliant and supplied in tape and reel packaging to facilitate automated assembly processes.

Feature Summary

• Provides effective high-frequency noise attenuation through magnetic material properties
• Utilizes a compact 1812 surface-mount form factor for space-constrained designs
• Supports single-channel signal or power line filtering applications

Applications

• Power supply input/output filtering
• Battery charger circuit protection
• Portable device signal integrity enhancement
• Energy-efficient system noise reduction

Procurement Notes

Verify the specific impedance tolerance and current rating requirements against your circuit design before ordering. Confirm that the 1812 package dimensions align with your PCB footprint specifications. Ensure the supplier provides documentation confirming RoHS compliance status for regulatory adherence. Check that the tape and reel quantity matches your production volume needs.

Selection Notes

Select this component when a 120-ohm impedance at 100 MHz is required for EMI suppression. The 1812 package size offers a balance between thermal performance and board space efficiency. Consider the single-circuit topology for simple filtering tasks where multi-stage solutions are unnecessary. Verify compatibility with standard surface-mount reflow soldering profiles.

Part Context

This ferrite bead belongs to Meritek's series of passive components focused on signal integrity and noise management. Ferrite beads function as frequency-dependent resistors, dissipating high-frequency energy as heat. They are essential for meeting electromagnetic compatibility standards in modern electronics. The 1812 package is widely adopted in consumer and industrial electronics for its reliability and ease of automation.
