The DIP-1998-04-1581-G is a thick film resistor network from TT Electronics, packaged in a Dual In-line Package (DIP). This network contains multiple resistors of equal value, designed to provide matched resistance values in a compact form factor. The "1581" likely refers to a resistance value of 1580 ohms (or 1.58 kOhms).

Applications:

• Pull-up/pull-down resistor networks
• Current limiting resistors
• Voltage dividers
• Logic circuits
• Operational amplifier circuits

Features:

• DIP package
• Number of resistors: Typically 8 or 16 (depending on the DIP size)
• Resistance value: 1.58 kOhms
• Tolerance: Typically ±2% or ±5%
• Power rating: Typically 0.125W per resistor
• Thick film technology

Benefits:

• Reduces component count and board space compared to using individual resistors.
• Provides matched resistance values, improving circuit performance.
• Simplifies PCB assembly.
• Offers a cost-effective solution for multiple resistor applications.

Additional Details:

The DIP-1998-04-1581-G resistor network offers a convenient way to implement multiple resistors with consistent values. The DIP package allows for easy insertion into through-hole PCBs. The thick film technology ensures stable and reliable resistance values over a wide temperature range.

The '04' in the part number likely refers to the number of pins on each side of the DIP package. The 'G' likely indicates the resistance tolerance or temperature coefficient. These networks are widely used in digital circuits for pull-up and pull-down applications, ensuring proper logic levels and preventing floating inputs.

The operating temperature range for these resistor networks is typically -55°C to +125°C. It's important to consider the total power dissipation of the network, ensuring that it does not exceed the specified rating. Derating curves are usually provided in the datasheet to account for operation at elevated temperatures.
