ILAS1206ER121V

Chip Ferrite Bead Overview

The ILAS1206ER121V is a multilayer ferrite chip bead array manufactured by Vishay / Dale. It features an SMD/SMT termination type and is housed in a 1206 (3216 metric) package with dimensions of 3.2 mm length, 1.6 mm width, and 0.8 mm height. The component provides four channels containing eight elements total. It exhibits an impedance of 120 Ohms at a test frequency of 100 MHz with a tolerance of 25%. The maximum DC current rating is 150 mA, and the maximum DC resistance is 200 mOhms. The operating temperature range spans from -55 C to +125 C.

Chip Ferrite Bead Procurement Notes

Verify the specific suffix and manufacturer designation when ordering, as Vishay and Vishay / Dale may produce distinct variants. Confirm RoHS compliance status through official documentation prior to integration. Ensure the selected packaging format matches production requirements. Cross-reference the exact part number against the latest datasheet to confirm electrical parameters and physical dimensions.

Chip Ferrite Bead Selection Notes

Select this component for applications requiring multi-line noise attenuation within a small footprint. The 1206 package size balances board space constraints with thermal performance. Evaluate the 150 mA current limit against peak signal line loads. Consider the 120 Ohm impedance value relative to target frequency attenuation needs. Verify compatibility with standard reflow soldering profiles for SMD assembly.

Chip Ferrite Bead Part Context

This ferrite bead array belongs to the broader category of passive components designed for high-frequency noise suppression. Unlike single-channel beads, this array integrates multiple filtering paths into one device. It serves as a critical element in maintaining signal integrity across parallel data lines. The multilayer technology enables precise impedance control within miniaturized form factors.
