TLH10UA2821R2

Overview

The TLH10UA2821R2 is a hybrid common mode choke coil manufactured by Taiyo Yuden, designed for through-hole mounting on printed circuit boards. It features a vertical package with four PC pins and measures 16.0 mm in width and 18.0 mm in length. The component provides a minimum common mode inductance of 2800 uH at 1 kHz and a typical normal mode inductance of 215 uH. It supports a maximum DC current of 1.2 A with a maximum DC resistance of 0.272 Ω per line. Rated for operation between -25°C and +105°C, it is suitable for AC line filtering applications.

Feature Summary

• Hybrid construction combining high common mode attenuation with controlled normal mode inductance
• Vertical through-hole mounting configuration for secure PCB integration
• Capable of handling up to 1.2 A DC current with low series resistance

Applications

• AC power line filtering
• Power supply input stages
• Electromagnetic interference suppression in electronic equipment

Procurement Notes

Verify the specific ordering suffix and datasheet revision before procurement, as component specifications may vary slightly between production batches or regional distributions. Confirm that the through-hole pin spacing matches the target PCB footprint design. Ensure the selected variant meets the required thermal and current ratings for the intended application environment. Cross-reference the manufacturer's official documentation to validate compliance with relevant safety and environmental standards.

Selection Notes

Select this component when high common mode noise rejection is required alongside moderate normal mode inductance in a through-hole form factor. The 1.2 A current rating suits medium-power AC line applications. Verify that the physical dimensions fit within the available board space. Consider the operating temperature range if the device will be exposed to elevated ambient temperatures during continuous operation.

Part Context

This part belongs to Taiyo Yuden's hybrid choke coil series, which integrates magnetic components to provide effective common mode filtering while minimizing impact on differential signals. The TLH10UA2821R2 utilizes a vertical leaded package, distinguishing it from surface-mount alternatives in the same functional category. It is engineered for reliability in standard industrial and consumer electronics environments.
