Tantalum Through-Hole Capacitors – Hermetically Sealed
T252 Series Axial MIL–PRF–39003 (CSR33 Style)
Overview
The hermetically sealed T252 Series solid tantalum
capacitors offer high capacitance-to-volume ratios and
are offered in standard MIL style A, B, C, and D cases.
They meet or exceed the environmental and mechanical
requirements of MIL–C–39003. Designed to operate from
−55°C to +125°C, The T252 Series exhibits exceptionally
low DC leakage, dissipation factor and impedance
characteristics. They are ideal for coupling, bypass, filtering
and timing circuits, and are excellent substitutes for wet
tantalum's in low voltage applications. These parts are
available in style CSR33 (T252 Series) per MIL–PRF–
39003/06 in capacitance value of 1.2 µF to 1000 µF and
working voltages pF 6 VDC to 50 VDC.
Benefits
• Taped and reeled per EIA Specification RS–296
• Marking per MIL–STD–1285
• Qualified to MIL–PRF–39003 (CSR33 Style)
• Failure rate options: Graded – B, C, D and G
Exponential - M, P, R, and S*
• Capacitance values of 1.2 μF to 1000 μF
• Tolerances of ±10% and ±20%
• Voltage rating of 6 – 50 VDC
• Operating temperature range of −55˚C to +125˚C
• Case sizes: A, B, C, D
*Failure rates apply to military products only
