TIP & RING CHIP CAPACITORS

CAPACITANCE SELECTION -1812-2225 SIZE

KEY FEATURES

• Blocks Off-hook DC Voltage

• Passes AC Ring Signal

• 250 VDC Ratings For Telecom Interface

• Choice of SMD Chip Sizes

• Low ESR versus Frequency

• Stable Temperature Performance (X7R)

The Tip & Ring MLCC series are designed specifically for

telecom ringer circuit applications where it is necessary to

provide a block of the line voltage (typically -48 VDC) while

passing the AC ringing voltage. These compact ceramic SMD

chips replace bulky leaded film caps saving board space and

stream-lining the assembly process.
