The TDK/Lambda TCR10S90 is a multilayer ceramic capacitor designed for EMI filtering and noise suppression in electronic systems. This radial lead component provides effective electromagnetic interference mitigation while maintaining high reliability across demanding operating conditions. The capacitor features Class 1 or Class 2 dielectric options with stable performance over temperature and voltage stress, making it suitable for power conversion, industrial control, and signal conditioning applications requiring proven noise rejection.

Technical Specifications

Capacitance & Tolerance
Capacitance specifications vary by class and rated value. Class 1 capacitors maintain drift within ±0.2% or ±0.05 pF (whichever is larger) with temperature coefficient calculated between 25°C and 85°C reference points. Class 2 tolerances and measurement conditions depend on rated capacitance threshold (10 µF and under versus over 10 µF). Electrical Performance
Insulation resistance meets minimum 10,000 MΩ or 500 MΩ·µF specifications when tested at rated voltage or 500 V DC for 60 seconds. Withstand voltage testing applies 2.5× rated voltage (for 100 V and under) or 1.5× (over 100 V) for 1–5 seconds without breakdown. Charge/discharge current is limited to 50 mA maximum. Dissipation factor and Q factor specifications are provided per measurement conditions in applicable standards. Operating & Storage
Class 1 dielectrics (X7R/X7S/X7T types) operate across −55°C to 125°C. Storage conditions are 5–40°C at 20–70% relative humidity with recommended term within 6 months of receipt. Reflow and lead termination soldering parameters are specified for manufacturing integration. Environmental Durability
Component withstands vibration testing (10–55–10 Hz, 1.5 mm amplitude for 2 hours) and temperature cycling. Moisture resistance is validated under defined temperature, humidity, and applied voltage stress. Solvent resistance is confirmed for PCB processing compatibility.
