Tantalum Chip Capacitors

B45294

Polymer; Low Profile; H_max= 2,0 mm; Ultra-Low ESR

New series

Construction

■ Polar tantalum capacitors with solid electrolyte

■ Tantalum polymer technology

(cathode consists of a solid conductive polymer)

■ Flame-retardant plastic case (UL 94 V-0)

■ Tinned terminals

■ Maximum height 2,0 mm

Features

■ High volumetric efficiency

■ Ultra-low ESR

■ Excellent solderability

■ Stable temperature and frequency characteristics

■ High ESR stability during temperature rise

■ High permissible ripple current

■ Only low derating necessary

■ Low self-inductance

■ High resistance to shock and vibration

■ No failure-mode ignition in high-surge current applications

■ Suitable for use without series resistor

(recommended operating voltage 0,8 · V_R)

■ Operating temperature – 55 … +105 °C

Applications

■ Telecommunications (e.g. mobile phones, private branch exchanges, PDA)

■ Data processing (e.g. laptops, main frames)

■ Measuring and control engineering

■ Automotive electronics (e.g. navigation systems, convenience electronics)

■ Medical engineering

■ Switch-mode power supplies with very high clock frequencies (300 kHz)

■ DC/DC converters

Soldering

Suitable for reflow soldering (IR and vapor phase) and wave soldering

Delivery mode

Taped and reeled in accordance with IEC 60286-3
