概述

Description

BLM18SG700TN1D is a Murata ferrite-bead EMI suppressor (SMD) from the BLM18SG family. It’s a 2‑terminal, 1808‑metric ferrite bead used to attenuate high‑frequency noise on power and signal lines. The part provides about 700 Ω impedance at 100 MHz with very low DC resistance, so it filters RF interference with minimal voltage drop. It’s RoHS compliant and designed for surface‑mount assembly. Typical applications include decoupling and EMI suppression in consumer electronics, automotive, and communications devices. Operating current and thermal behavior depend on board design and use conditions.

Features

- SMD ferrite bead for EMI/RFI suppression
- Impedance: 700 Ω at 100 MHz (typical)
- Very low DC resistance
- 2-terminal, no polarity
- Reflow-solderable, RoHS compliant
- Operating temperature: −55 °C to +125 °C
- MnZn ferrite material
- Suitable for power and signal-line noise filtering on PCBs

Package

Surface-mount ferrite bead in an 1812 (approx. 4.6 × 3.0 mm) package.

Pinout

- Pin count: 2 pins (single-line ferrite bead)
- Function: SMD ferrite bead used for EMI/RFI noise suppression; provides high-frequency impedance to attenuate noise while allowing DC/current to pass.

Manufacturer

- Manufacturer: Murata Manufacturing Co., Ltd.
- What kind of company: A Japanese multinational electronics components company that designs and manufactures passive components (e.g., ferrite beads, capacitors, inductors), sensors, and modules for global markets.

Application

BLM18SG700TN1D is a ferrite bead for EMI/RFI suppression. Applications: high-frequency noise filtering on power rails and data lines; decoupling for DC-DC converters and regulators; EMC improvement in mobile devices, consumer electronics, computers and networking gear; EMI control in automotive/industrial electronics.
