4818T-2-1002FB

4818T-2-1002FB Description

The 4818T-2-1002FB from Bourns Inc. is a high-precision thin-film resistor network housed in an 18-pin DIP (Dual In-Line Package). Designed for applications demanding tight tolerance and stability, this obsolete model features a 10 kΩ (1002FB) resistance value per element, making it suitable for legacy or specialized circuits. Its tube packaging ensures mechanical protection during handling, while its Moisture Sensitivity Level (MSL) 1 (Unlimited) rating guarantees reliability in non-harsh environments. Though marked obsolete, this component remains a robust choice for systems requiring proven performance.

4818T-2-1002FB Features

• Thin-Film Technology: Delivers superior accuracy (±0.1% typical), low TCR (Temperature Coefficient of Resistance), and long-term stability compared to thick-film alternatives.
• 18-Pin DIP Configuration: Ideal for breadboarding, prototyping, or integration into legacy PCBs requiring through-hole mounting.
• 10 kΩ Resistance per Element: Balanced impedance for signal conditioning, voltage division, and precision analog circuits.
• MSL 1 (Unlimited): No baking required prior to assembly, reducing processing time and cost.
• Obsolete Status: Best suited for maintenance, repairs, or designs with existing dependencies on this specific model.

4818T-2-1002FB Applications

This resistor network excels in:

• Legacy Industrial Controls: Replacement or repair of aging equipment where design consistency is critical.
• Precision Instrumentation: Signal attenuation in test/measurement devices, DACs (Digital-to-Analog Converters), and sensor interfaces.
• Audio/Video Systems: Impedance matching in high-fidelity audio circuits or broadcast equipment.
• Medical Electronics: Low-noise, stable performance in diagnostic devices where component reliability is paramount.

Conclusion of 4818T-2-1002FB

While the 4818T-2-1002FB is obsolete, its thin-film precision, DIP packaging, and 10 kΩ resistance make it a dependable choice for niche applications. Engineers seeking a proven solution for legacy systems or low-volume production will find its performance benefits outweigh its discontinued status. For new designs, Bourns may recommend modern alternatives with similar specifications but enhanced availability.
