概述

Description

The SDR0403-101KL is a type of surface mount inductor, commonly used in electronic circuits for various applications including power management, filtering, and signal processing. The designation "SDR" typically indicates a series or family of inductors, while "0403" refers to its package size, measured in inches (0.04 x 0.03 inches). The "101" denotes the inductance value, which is 100 µH (microhenries), and "KL" may refer to specific characteristics such as tolerance or temperature coefficient.
These inductors are designed for high efficiency and compact size, making them suitable for use in mobile devices, telecommunications, and consumer electronics. They help in reducing noise and stabilizing voltage levels in circuits. When selecting an inductor like the SDR0403-101KL, considerations include current handling capability, DC resistance, and operating temperature range to ensure optimal performance in the intended application.

Features

The SDR0403-101KL is an inductor characterized by its compact size and efficient performance. Key features include:
1. Inductance Value: 100 µH, ideal for filtering and energy storage applications.
2. Current Rating: High saturation current capability, enhancing reliability in various circuits.
3. DC Resistance (DCR): Low DCR, which minimizes power loss and heat generation during operation.
4. Package Size: Designed in a small footprint, making it suitable for space-constrained applications.
5. Temperature Range: Operates effectively across a wide temperature range, ensuring stability in diverse environments.
6. Shielding: Often includes magnetic shielding to reduce electromagnetic interference (EMI).
These features make the SDR0403-101KL suitable for use in power supplies, automotive applications, and other electronic devices requiring efficient energy management.

Package

The SDR0403-101KL is typically packaged in a 0403 size (1.0 mm x 0.5 mm) SMD (Surface Mount Device) format. It is a fixed inductance type component, commonly used in various electronic applications for filtering and energy storage.

Pinout

The SDR0403-101KL is a type of resistor, specifically a surface-mount device (SMD) resistor with a resistance value of 100 ohms (10 x 10^1 ohms) and a tolerance of ±10%.
