Descripción general

Description

BLM31KN271SH1L is a Murata BLM31-series surface-mount ferrite-bead EMI filter. The “271” code means about 270 Ω impedance at 100 MHz. In a 1206-size package, it provides high-frequency noise suppression with very low DC resistance, making it suitable for filtering glitches on power rails or signal lines. It is RoHS-compliant and intended for SMD assembly. Use it when you need to attenuate conducted EMI without causing a significant voltage drop.

Features

Features of BLM31KN271SH1L:
- SMD ferrite bead for EMI suppression (two-terminal)
- Impedance: 270 Ω at 100 MHz (code 271)
- Package: BLM31 size (compact 3.2 × 1.6 mm class)
- Low DC resistance for minimal voltage drop
- Broad-band high-frequency noise suppression
- RoHS compliant (Pb-free)
- Operating temperature typically -55°C to +125°C
- Suitable for both power and signal lines to reduce EMI

Package

SMT ferrite bead in the BLM31 series; a surface-mount package (roughly 1206 footprint).

Pinout

- Pin count: 8 pins (4 channels, 2 pins per channel)
- Function: 4-channel ferrite-bead EMI filter network (ferrite beads in series on four lines) for noise suppression; the “271” indicates ~270 Ω impedance at 100 MHz per channel.

Manufacturer

- Manufacturer: Murata Manufacturing Co., Ltd.
- What kind of company: A Japanese multinational electronics components company that designs and manufactures passive components and materials (e.g., ferrite beads, capacitors, inductors, sensors). It is one of the world's largest suppliers of chip ferrite beads and other ceramic-based components, publicly traded on the Tokyo Stock Exchange.

Application

Application areas:
- High-frequency EMI suppression on power rails and data/signal lines
- Noise filtering and decoupling in portable electronics and automotive systems
- Used on motherboards, smartphones, tablets, laptops, wearables, TVs, networking equipment, and automotive ECUs

Equivalent

Direct cross: Murata BLM31KN271SN1L (identical 1206 ferrite bead, 270 Ω @100 MHz). Other vendors with the same spec (1206, 270 Ω @100 MHz) include TDK ZCAT2710 series and comparable ferrite beads from Vishay/Würth/Yageo. Confirm datasheet impedance at 100 MHz and package 1206 for exact cross.
