Summary

KEMET T551B107M040AH4251 is used in Tantalum - Polymer Capacitors category where derating, temperature behavior, and mechanical fit affect long-term stability. Key specs include Description (CAP TANT POLY 100UF 40V AXIAL), Capacitance (100 µF), Rated voltage (40 V), Tolerance (±20%), and Temperature (-55°C ~ 125°C).

Selection Notes
  • For T551B107M040AH4251, validate the operating temperature range (-55°C ~ 125°C) for your environment and margin.
  • Confirm Size / Dimension (0.312" Dia x 0.641" L (7.92mm x 16.28mm)) meets your design constraints and system-level expectations.
  • Ensure the package/case (Axial, Can) and land pattern match your PCB layout before procurement.
  • Verify the capacitance value (100 µF) under DC bias and temperature as applicable.
Alternates & Substitutions
  • In Tantalum - Polymer Capacitors, confirm that alternates preserve startup states and fault behavior so system behavior does not change quietly.
  • Confirm the real operating corners (temperature -55°C ~ 125°C) and avoid swaps that only work at typical conditions.
  • For capacitor substitutions, match capacitance 100 µF, rated voltage 40 V, tolerance ±20% and confirm DC-bias/temperature effects if applicable.
  • If substitutions are likely, write down the non-negotiables and re-check them when the supply chain changes, not after field failures.
FAQ

Application Scenarios

Selecting KEMET T551B107M040AH4251 for Tantalum - Polymer Capacitors usually comes down to meeting the system constraints that matter most: limits, interfaces, and testability in the real build. Selection depends on ESR/ESL, ripple current, temperature behavior, dielectric stability, and lifetime under stress. Their placement and derating strategy often decide whether a design passes EMC and survives long-term thermal exposure. Within telecom and data center power, impedance and ripple margins influence stability in dense, high-current boards. In motor-control power stages, capacitors are qualified for ripple current and heat rise because stress is repetitive and cumulative. Across instrumentation, stable dielectric behavior prevents drift that would otherwise limit measurement repeatability.

Compatibility Advice
  • For KEMET T551B107M040AH4251 in Tantalum - Polymer Capacitors, confirm tolerance, derating, ESR or impedance versus frequency, and thermal rise on the assembled PCB. This keeps acceptance criteria measurable and repeatable.
Project Fit
  • Best fit for Tantalum - Polymer Capacitors when you can verify tolerance, derating, ESR or impedance versus frequency, and thermal rise on the assembled PCB.
