TLH10UB3521R0

Overview

The TLH10UB3521R0 is a hybrid choke coil manufactured by Taiyo Yuden, designed for common mode noise suppression in electronic circuits. This through-hole component features a dual-channel configuration with a common mode inductance of 3500 µH (minimum) and a normal mode inductance of 232 µH (typical). It operates within a temperature range of -25°C to +105°C and supports a maximum current of 1A. The DC resistance is specified at a maximum of 0.422 Ω, with voltage ratings of 250V. The unit utilizes a 16.0 x 18.0 mm case size and complies with RoHS standards.

Feature Summary

• Hybrid construction combining common mode filtering with specific normal mode characteristics
• Through-hole mounting design ensuring stability on printed circuit boards
• High-temperature operational capability suitable for demanding environments

Applications

• Power supply input filtering for general household appliances
• Noise suppression in industrial equipment power lines
• Common mode interference reduction in video and TV sets

Procurement Notes

Verify the phase-out status indicated in available documentation before finalizing procurement plans. Confirm that the through-hole termination style matches the target PCB layout requirements. Ensure the 1A current rating and 0.422 Ω DC resistance specifications align with the circuit design constraints. Validate compliance with RoHS directives if required by the end product regulations.

Selection Notes

Select this component when high common mode attenuation is required alongside moderate normal mode inductance. The hybrid nature distinguishes it from standard chokes, offering balanced performance for mixed-mode noise. Consider the physical dimensions and through-hole mounting method during mechanical integration. Evaluate the thermal performance given the 105°C upper operating limit for high-load applications.

Part Context

Taiyo Yuden produces a range of passive components including inductors and capacitors. The TLH series represents their hybrid choke offerings, distinct from standard radial or axial inductors like the LHL or LAV series. These components are engineered for robust noise suppression in power and signal lines, catering to both consumer electronics and industrial sectors requiring reliable EMI/RFI mitigation.
