Film Capacitors – Made in Germany

SMD capacitors

Fields of Application: Automotive, Power, Medical, Consumer, Telecom/Data
Product Type Application Function Circuit Application Waveform Requirements Special Characteristics
SMD-PET
SMD-PEN
SMD-PPS		 Blocking/Coupling

High-pass filter:

– preventing DC voltages
– transferring AC voltages
– High insulation resistance
– Low self-inductance (to observe voltage rating)
  • Operating temperatures up to 125°C (SMD-PET, SMD-PEN) and 140°C (SMD-PPS)
  • Suitable for lead-free soldering at elevated processing temperature Tpeak = 250°C (SMD-PEN, SMD-PPS)
  • Suitable for filtering due to low dissipation factor (SMD-PPS)
Compared to ceramic SMDs (MLCC):
  • No internal cracks or delamination
  • ΔC/C over temperature: very low (SMD-PET, SMD-PEN) or extremely low (SMD-PPS)
  • Self-healing capability -> high withstanding voltage, high reliability
Bypass/Decoupling

Low-pass filter:

– suppressing transmission of high frequencies (AC voltages)
– High insulation resistance
– Low self-inductance
Smoothing
– Smoothing of pulsating DC-voltages from AC-rectifier
– Comparably high capacitance
– Low dissipation factor (to obseve frequency)
SMD-PPS Band-pass filter (e.g. audio, TV)
– pass frequencies within a certain range
– attenuate frequencies outside that range
– Low dissipation factor
– Stable capacitance
Band-stop filter (e.g. audio, TV)
– attenuate frequencies within a specific range
– pass frequencies outside that range
– Low dissipation factor
– Stable capacitance
