Thermal, Components, and Reliability

Published tools in this category solve distinct design decisions. Each keeps its assumptions, limits, and next decision visible.

Datasheet-driven estimate

Junction-temperature estimator

Estimate steady-state semiconductor junction temperature from power, a stated reference temperature, thermal metric, and optional limit.

Decision comparison

Component derating planner

Express a stated component stress as rating utilization and arithmetic margin before policy and transient adjustments.

Datasheet-driven estimate

Transient thermal impedance

Estimate junction rise for one pulse from power, a stated transient thermal impedance, and reference temperature.

Datasheet-driven estimate

Ceramic capacitor DC-bias derating

Estimate a first-pass minimum ceramic-capacitor value from entered nominal capacitance, DC-bias retention, and tolerance.

Exact model relationship

FIT, MTBF, and reliability converter

Convert a stated constant FIT rate into MTBF, mission survival, and expected population failures under an exponential model.

Standard approximation

Arrhenius acceleration factor

Estimate comparative temperature acceleration and equivalent use exposure from Celsius temperatures, activation energy, and stress time.
