100 tip & ring multilayer ceramic chip capacitors avx tip & ring or ring detector multilayer ceramic chip capacitors are designed as a standard telecom filter to block -48 volts dc telephone line voltage and pass subscribers ac signal pulse (16 to 25hz, 70 to 90vrms). the typical ringing signal is seen on figure on page 101. the ringer capacitors replace large leaded film capacitors and are ideal for telecom/modem applications. using avx tip & ring capacitors not only saves valuable real estate on the board and reduces the weight of overall product, but also features standard surface mounting capabilities, so critical to new and compact designs. the avx tip & ring capacitors are offered in standard eia sizes and standard values. they offer excellent high frequency performance, low esr and improved temperature performance over film capacitors. how to order 1812 p c 104 k a t 1 a avx voltage temp capacitance capacitance test packaging special style 250 vdc coefficient code tolerance level 1 = 7" reel code 0805 telco x7r (2 significant k = 10% a = standard 3 = 13" reel a = standard 1206 rating digits + no. m = 20% 9 = bulk 1210 of zeros) 1808 examples: 1812 1,000 pf = 102 1825 22,000 pf = 223 2220 220,000 pf = 224 2225 1 f = 105 style 0805 1206 1210* 1808* 1812* 1825* 2220* 2225* (l) length 2.01 0.20 3.20 0.20 3.2 0.20 4.57 0.25 4.50 0.30 4.50 0.30 5.60 0.30 5.60 0.25 (0.079 0.008) (0.126 0.008) (0.126 0.008) (0.180 0.010) (0.177 0.012) (0.177 0.012) (0.220 0.012) (0.220 0.010) (w)width 1.25 0.20 1.60 0.20 2.50 0.20 2.03 0.25 3.2 0.20 6.34 0.30 5.10 0.40 6.35 0.25 (0.049 0.008) (0.063 0.008) (0.098 0.008) (0.080 0.010) (0.126 0.008) (0.252 0.012) (0.200 0.016) (0.250 0.010) (t) thickness 1.30 max. 1.50 max. 1.78 max. 1.78 max. 2.00 max. 2.00max. 2.00 max. 2.00 max.
