102 tip & ring tin/lead termination b multilayer ceramic chip capacitors avx corporation will support customers for commercial and military multilayer ceramic capacitors with a termination consisting of 5% minimum lead. this termination is indicated by the use of a b in the 12th position of the avx catalog part number. this fulfills avxs commitment to providing a full range of products to our customers. avx has provided in the following pages, a full range of values that we are offering in this b termination. avx tip & ring or ring detector multilayer ceramic chip capacitors are designed as a standard telecom filter to block -48 volts dc telephone line volt- age and pass subscribers ac signal pulse (16 to 25hz, 70 to 90 vrms). the typical ringing signal is seen on figure on page 103. the ringer capacitors replace large leaded film capacitors and are ideal for telecom/modem applica- tions. using avx tip and ring capacitors not only saves valuable real estate on the board and reduces the weight of the 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. style (size) ld05 (0805) ld06 (1206) ld10* (1210) ld08* (1808) ld12* (1812) ld13* (1825) ld20* (2220) ld14* (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.
