# 450 ohm termination resistor

470 Ohms Resistors are available at Mouser Electronics. Mouser offers inventory, pricing, & datasheets for 470 Ohms Resistors.

Non-Inductive Resistors at Parts Express. Non-inductive wirebound & low-inductive wirebound compositions. Non-inductive resistor for audio & crossover networks. The terminating resistor is to some extent determined by the impedance of the feedline. With 300 ohm twin lead, the optimum resistor value is about 400 ohms. With 450 ohm line, a 500 ohm resistor is fine and 600 ohm line needs 650 ohms. Keep in mind that 50% duty cycle of CW or even lower of SSB wattage needed in the resistor. Total Balun/Terminator SWR with 50W resistor Total Balun/Terminator SWR with 200W resistor Balun Box Transformer type: 50 ohms to 600 ohms voltage balun. Uses Philips Ferrite Toroid 4C64, 36x23x15mm, 2 to 30 MHz. Primary winding is 2x6 turns Suhner Radox 125, 0.5 mm2. Secondary winding is 2x11 turns Suhner Radox 125, 0.5 mm2.

The HART Foundation’s website has a technical specification that states that the minimum loop resistance needed is 230 ohms. A 250 ohm resistor is commonly used because 250 ohm resistors work for that purpose and are typically available in the instrument shops where these types of bench tests are done.

The resistive component of the source impedance ranged from 450 to over 1400 Ohms, while the reactive component ranged from +j250 to -j700 Ohms across the frequency span. These ranges must be considered tentative, since the check points are 1 MHz apart.
