Special Characteristics

SMD-PET
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) and 140°C (SMD-PPS)
Suitable for lead-free soldering at elevated processing temperature T_peak = 250°C (SMD-PPS)
Suitable for filtering due to low dissipation factor (SMD-PPS)

Compared to ceramic SMDs (MLCC):

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
