ESMIT-190NP

Overview

The ESMIT-190NP is a surface-mount audio and signal transformer manufactured by Sumida America Components Inc. It belongs to the CBM series and features a single-channel configuration with SMD/SMT termination. The component has an inductance of 120 µH, operates within a frequency range up to 100 kHz, and provides an insulation voltage of 3.75 kV. It functions reliably across a temperature range from -40°C to +125°C. The physical dimensions are 7.1 mm in length, 5.2 mm in width, and 3.5 mm in height, housed in an SMD-4 package.

Feature Summary

Surface-mount construction for automated PCB assembly
High insulation voltage capability for signal isolation
Wide operating temperature range for environmental stability

Applications

Modem signal transmission circuits
Audio signal processing interfaces
Data communication line isolation

Procurement Notes

Verify the specific suffix designation against official Sumida documentation to ensure correct electrical characteristics. Confirm RoHS compliance status through current manufacturer declarations. Validate that the supplier source provides authentic components matching the specified part number and series requirements.

Selection Notes

Select this component when high insulation voltage and wide thermal tolerance are required for modem or audio applications. The compact SMD-4 footprint suits space-constrained designs. Ensure the circuit design accommodates the 120 µH inductance and 100 kHz frequency limitations for proper signal integrity.

Part Context

This transformer is part of Sumida's CBM series, designed specifically for pulse and signal transformation tasks. It serves as a critical isolation component in telecommunications and data exchange hardware, providing reliable performance in demanding electronic environments.
