HHM1523C1

Balun Overview

The HHM1523C1 is an LTCC balun transformer manufactured by TDK Corporation, designed for signal conditioning in RF applications. It operates within a frequency range of 880 MHz to 960 MHz, centered around 880-960 MHz. The component provides impedance transformation between 50 Ohms and 100 Ohms. It features a maximum insertion loss of 1.1 dB and a minimum return loss of 10 dB. The phase difference is specified as 180° ±10°. Packaged in a 0805 (2012 metric) surface-mount case, it supports board mount installation. The device functions within an operating temperature range of -40°C to +85°C.

Balun Procurement Notes

Verify component authenticity through authorized distributors due to end-of-life status. Confirm RoHS3 compliance and MSL level 1 handling requirements during storage. Check datasheet revisions for any specification updates prior to integration. Ensure supply chain stability as manufacturer discontinuation may affect long-term availability. Validate package dimensions against PCB footprint specifications before procurement.

Balun Selection Notes

Select this component when designing circuits requiring 50 to 100 Ohm impedance transformation in the 880-960 MHz range. Consider the 0805 package size for space-constrained layouts. Evaluate thermal performance within the -40°C to +85°C operating window. Assess insertion loss impact on system sensitivity. Verify compatibility with standard SMT assembly processes for reliable soldering.
