Core mitigation strategies involve humidity-resistant component selection and protective manufacturing processes:

① Prefer humidity-resistant models: e.g., CSCF series ferrite inductors — MnZn ferrite cores resist oxidation/rusting under high humidity, fundamentally reducing moisture-induced drift in L and Q values.

② Implement board-level protection: Apply coating post-PCB assembly to form an effective moisture barrier — a proven and widely adopted secondary measure.

③ Verify critical certifications: Confirm that inductors pass 85°C/85% high-humidity testing or possess relevant MSL (Moisture Sensitivity Level) ratings — direct evidence of humidity resilience and parameter stability.
