To ensure consistent performance and durability across a range of operating conditions, our inductors and transformers are being evaluated using the ICE Reliability Test Standard — a rigorous internal benchmark developed to simulate real-world environmental and assembly stresses. Each test is designed to validate mechanical integrity, thermal resilience, and electrical stability under demanding scenarios.

Environmental & Soldering Reliability

A series of stress tests were performed to assess product reliability under harsh environmental conditions. Dry Heat, Low Temperature, and Damp Heat tests simulated extended exposure to high temperatures, freezing conditions, and humid environments — typical of sealed enclosures, outdoor installations, and poorly ventilated spaces. Each test ran for 96 hours under controlled conditions. All samples maintained structural integrity and stable electrical performance, with no visible damage or measurable drift, confirming resistance to passive thermal and moisture stress.

High Temperature Operational Life testing validated consistent electrical output under continuous load at elevated temperatures; additionally, Thermal Shock testing involved 100 rapid cycles between −40 °C and +125 °C, confirming mechanical resilience to thermal expansion and contraction.

Solderability and Resistance to Soldering Heat tests demonstrated strong wetting behavior and heat tolerance during assembly. All units met or exceeded coverage requirements, with no signs of cracking, delamination, or performance degradation. These results support compatibility with automated soldering processes and suitability for high-reliability applications.
