Part Number Ordering Information, example and explanation:   M39003/10-3009S where,

M39003	/10	-3009	S
Military Specification Number	Detail Specification Number	Four-digit dash number which uniquely identifies the capacitance, tolerance, rated dc voltage, dc leakage, dissipation factor and failure rate level	Configuration:  H = internal solder melt point of 221°C minimum (/9 parts only) S = sleeved case (/10 parts only) U = unsleeved case (/10 parts only)

  Part number ordering options are developed using the following criteria:

Style	Detail Specification Sheet	Available Tolerances		Failure Rate Levels
CSR13	MIL-PRF-39003/1	10%		B = 0.1%/1000 hours (Level 2)
CSR09	MIL-PRF-39003/2	10%, 20%		C = 0.01%/1000 hours (Level 1)
CSR21	MIL-PRF-39003/9	5%, 10%, 20%
CSS13	MIL-PRF-39003/10	10%
CSS33	MIL-PRF-39003/10	10%
