TRW - H18000 – Capacitor Polystyrene, 18000pF, (0.018uF).

TRW - H18000 – Capacitor Polystyrene, 18000pF, (0.018uF). Polystyrene capacitors are prized for excellent stability, low distortion, high insulation resistance, and low dielectric absorption, making them ideal for high-fidelity audio, precision timing, and critical analog circuits, though they have a low maximum operating temperature (around 85°C) and are prone to heat damage from soldering. Key properties include high capacitance stability with temperature, low loss factor (high Q), and suitability for low-capacitance, high-stability needs, often replacing ceramic or mica capacitors in demanding applications. TRW became ASC Capacitors Key Electrical Properties • Low Distortion & Low Loss: Excellent for audio coupling and filters due to minimal signal loss and distortion. • High Insulation Resistance: Very high resistance, leading to low leakage. • Low Dielectric Absorption: Extremely low, crucial for precise timing and sample-and-hold circuits. • Excellent Stability: High capacitance stability with temperature and frequency changes. • Low Temperature Coefficient: Small, stable capacitance change over temperature, down to ±1% from -55°C to +85°C. • High Q Factor: Good for resonant circuits. • Capacitance: 18 nF (18,000 pF), 0.018uF • Capacitor Construction: Polystyrene Film / Foil • Termination Style: Axial (center) These capacitors are highly sought after for guitar amplifiers and high-fidelity audio due to their excellent tone characteristics, a hallmark of vintage US-made parts. Also found in vintage audio, radio, or other electronic applications. Made in USA Genuine Vintage TRW – No Counterfeits – No China – No Delays – No Disappointments. New Old Stock
