Murata Power Solutions Through Hole Pulse Transformer 0.0423611111 Turns Ratio, 2 mH Primary Inductance, 1Ω Primary 78250C

Murata Power Solutions 78250C Through Hole Pulse Transformer offers precise electrical isolation and signal conditioning with a turns ratio of 0.0423611111, primary inductance of 2 mH, and primary DC resistance of 1Ω. Designed with a through hole mounting style and 6 pins, this low profile pulse transformer ensures reliable and secure connection on printed circuit boards.

Operating efficiently within a temperature range from -40°C to 85°C, it supports a maximum current rating of 300mA. The compact dimensions of 9mm length and 10.19mm width allow integration into space-constrained electronic designs without compromising performance. Its low leakage inductance of 3μH reduces unwanted signal distortion.

This pulse transformer complies with stringent RoHS and UL standards, confirming its suitability for use in industrial, commercial, and communication device applications requiring safe electrical isolation. It is especially optimized for RS-232 communications isolation, functioning perfectly as an isolation converter transformer in conjunction with Maxim Integrated circuits like the MAX251 (stock no. 540-2142).

The pin termination facilitates straightforward soldering, assuring secure mechanical and electrical bonding on PCBs with standard 2.54mm pin pitch. Its 4 kVrms isolation voltage rating offers robust protection against high voltage spikes and noise in sensitive circuits.

Maximum isolation voltage of 4 kVrms ensures high-level electrical safety. Through hole mount type with 6 pins enables durable PCB connections. Very low primary DC resistance and leakage inductance minimize losses and signal interference.

Complies with RoHS and UL, adhering to industrial safety and environmental standards. Compact footprint supports streamlined circuit board layouts. Temperature rating from -40°C to 85°C accommodates diverse operating environments.

Ideal for RS-232 communications and isolation converter applications.

As a high-quality electronic component, this transformer is widely applied in industrial control systems, telecommunications, power supply isolation circuits, and other electrical apparatus requiring signal integrity and device protection. Customers can rely on Murata Power Solutions for consistent performance and adherence to quality standards.
