A COMPACT COIL ASSEMBLY FOR TRANSIENT VOLTAGE PROTECTION

摘要

A compact coil assembly (10) is provided for protecting electrical components from transient voltage surges. The assembly (10) includes a bobbin (12) having a cylindrical core (14) with two ends. A first and second flange (20, 22) are each perpendicularly mounted and extended outwardly from one of the ends. A lead pin (30) is perpendicularly upstanding on the top surface of the first flange (20). The first flange (20) has parallel outer and inner walls (26, 28) defining a channel (24) therebetween. The inner wall (28) has a slot (32) therethrough. The slot (32) is positioned on the top surface (34) of the first flange opposite the lead pin (30). The channel (24) extends from the lead pin across to the end of the slot (32) near the core (14). The width of the channel (24) and the slot are adapted for guiding a winding wire therethrough.
