Tantalum chip capacitors
SpeedPower, Low ESR
Construction
Polar tantalum capacitors with solid
electrolyte
Conventional, optimized TaMnO
2
technology
Flame-retardant plastic case (UL 94 V-0)
Optionally tinned or gold-plated terminals
Features
B45197A, B45198R, B450, B451
Wide variety of Low ESR values
High ripple current capability
High volumetric efficiency
Excellent solderability
Stable temperature and frequency characteristics
Low leakage current, low dissipation factor
Low self-inductance
High resistance to shock and vibration
Suitable for use without series resistor (recommended operating conditions see
www.epcos.com/tantalum_gti, section 4.4)
Lead-free and material content compatible with RoHS
Some partnumbers are only available in M (±20%) tolerance; these types have a maximum
capacitance drift at +125
°C
of +20%
Applications
Telecommunications (e.g. mobile phones, infrastructure)
Data processing (e.g. laptops, mainframes)
Measuring and control engineering (e.g. voltage regulators)
Automotive electronics (e.g. navigation systems, electronic control units)
Medical engineering
DC/DC converters
Soldering
Suitable for reflow soldering (IR and vapor phase, in compliance with JEDEC J-STD-020 C) and
wave soldering
Delivery mode
Taped and reeled in accordance with IEC 60286-3
