These stacked multilayer ceramic capacitors provide high capacitance solutions at ultra high temperature ratings for down hole and similar extreme environment applications. The multilayer ceramic dielectric also delivers lower ESR and DC leakage current ratings, better capacitance stability over frequency and substantially higher current ratings than comparable wet tantalum devices.
- AVX SMX style are ideally suited for applications for applications up to 200°C. Capacitance range is 0.01µF to 270µF and working voltage range 25Vdc to 500Vdc. Dielectric types are COG (NPO) & VHT.
2. Johanson Dielectrics High Temperature Stacked MLC capacitors are also suitable for applications up to 200°C. Capacitance range is 0.022µF to 47µF and working voltage range 50Vdc to 200Vdc. Dielectric types are NPO & X7R.
3. Presidio Components High Temperature SMPS Stacked Capacitors (HTS type) are suitable for applications up to 250°C. Capacitance range is 0.006µF to 120µF and working voltage range 25Vdc to 500Vdc. Dielectric types are NPO, XHT & X7R (pages 9 – 12 of their high temperature capacitor catalog).
