Capacitor MTBF, MIL-HDBK-217, Rev. F - Notice 2

Learn about Environmental Test Chambers

To calculate the MTBF and failure rate of a capacitor using the MIL-HDBK-217F failure model, enter its parameters in the following table.

Parameter ValueNotes
Capacitor Style See Capacitor Style Table
Capacitance (µF)  
Quality (1)
Environment Environment codes
Capacitor Rated Power (V)  
Applied (Operating) Power (V) The sum of applied DC voltage and peak AC voltage
Temperature (°C) (2)
Effective Resistance Between Capacitor and Power Supply (Ω) Only needed for tantalum capacitors


(1) Established reliability styles are failure rate graded (D, C, SP, etc) based on life testing defined in the applicable military device specification. This category applies only to three-letter styles with an "R" suffix. Also see the quality table.

(2) Capacitor Ambient Temperature.
