Table 4. Input Selection
The transistor must be a small-signal type with a base
resistance less than 100Ω. Tight specifications for for-
ward current gain (+50 to +150, for example) indicate
that the manufacturer has good process controls and
that the devices have consistent V
(See Table 6 for recommended devices.)
For heatsink mounting, the 500-32BT02-000 thermal
sensor from Fenwal Electronics is a good choice. This
device consists of a diode-connected transistor, an alu-
minum plate with screw hole, and twisted-pair cable
(Fenwal Inc., Milford MA, 508-478-6000).
For remote-sensor distances greater than 8 inches, or
in particularly noisy environments, use a twisted-pair
cable. A practical length is 6 feet to 12 feet. For longer
distances, the best solution is a shielded twisted-pair
cable such as that used for audio microphones. For
