Yes, Samwha provides Spice models for major capacitor series: Available Models - Aluminum electrolytic capacitors (WH, WL, WD series), Solid polymer capacitors (PH, PK series), Film capacitors (MPP, MPET series). Model Types - Basic RLC model for frequency response simulation, Advanced behavioral model including temperature and DC bias effects, Thermal model for temperature rise calculations. Model Parameters - ESR vs frequency and temperature, ESL (equivalent series inductance), Capacitance vs temperature and DC bias, Leakage current vs temperature. How to Request - Contact our technical support with your specific part numbers. Models are provided as subcircuit files compatible with major Spice simulators (LTspice, PSpice, Multisim). Limitations - Models are representative of typical production units. For critical applications, verify with actual component measurements.

Contact technical support to request Spice models for your specific capacitor part numbers.
